NBody Simulations of Alternate Gravity Models
 Phys. Rev
, 2006
"... Theories in which gravity is weaker on cosmological scales have been proposed to explain the observed acceleration of the universe. The nonlinear regime in such theories is not well studied, though it is likely that observational tests of structure formation will lie in this regime. A class of alter ..."

of alternate gravity theories may be approximated by modifying Poisson’s equation. We have run Nbody simulations of a set of such models to study the nonlinear clustering of matter on 1100 Mpc scales. We find that nonlinear gravity enhances the deviations of the power spectrum of these models from standard

"... ABSTRACT The knowledge of the insitu stress field in rock masses is in general of crucial importance in various areas of geoengineering, such as mining or civil underground excavations, hydrocarbon extraction, CO2 storage, hydraulic fracture operations, etc. In the context of the Finite Element ..."

to incorporate all the information available, aside of course from the most basic method consisting of using vertical stresses due to gravity and horizontal due to K 0 . In this paper, the various options available are discussed and compared, and one new alternative procedure is developed based on Airy stress
Einsteinian Strengths and Dynamical Degrees of Freedom for Alternative Gravity Theories
, 2002
"... In the paper we present the results of the our calculations of the Einsteinian strengths SE(d) and numbers dynamical degrees of freedom NDF(d) for alternative gravity theories in d ≥ 4 dimensions. At the first part we consider the numbers SE(d) and NDF(d) for metriccompatible and quadratic in curva ..."

Current tests of alternative gravity theories: the Modified Newtonian Dynamics case
, 2006
"... We address the possibility of taking advantage of high accuracy gravitational space experiments in the Solar System and complementary cosmological tests to distinguish between the usual general relativistic theory from the alternative modified Newtonian dynamics paradigm. Key words: ..."

Empirical constraints on alternative gravity theories from gravitational lensing
, 2001
"... If it is hypothesised that there is no dark matter then some alternative gravitational theory must take the place of general relativity (GR) on the largest scales. Dynamical measurements can be used to investigate the nature of such a theory, but only where there is visible matter. Gravitational len ..."

Structure Formation in Alternative Gravity with a Vector Field: I. Equations for F(K) gravity with a K4 term
, 711
"... We study an extension to a recent class of F(K) gravity model, which gives MONDlike effects in galaxies but in covariant form, especially including a previously neglected K4 term. These models have fewer degrees of freedom than Bekenstein’s (2004) TeVeS theory due to a fixed norm of the timelike ..."

Using the gravity equation to differentiate among alternative theories of trade
 Canadian Journal of Economics
, 2001
"... The simple gravity equation explains a great deal about the data on bilateral trade flows, and is consistent with several theoretical models of trade. We argue that alternative theories nevertheless predict subtle differences in key parameter values, depending on whether goods or homogeneous or diff ..."

Avoiding Dark Energy with 1/R Modifications of Gravity,” astroph/0601672
"... The case for alternate gravity is easily made. The best that can be done from observing cosmic motions is to infer the metric gµν in some coordinate system. From this one can reconstruct the Einstein tensor and then ask whether or not ..."
